1. A method of wireless communication, the method comprising:
detecting, by a wireless network, a network congestion condition;
detecting, by the wireless network, a failed attempt, by a user equipment (UE), to initiate a first data session over a packet data network (PDN) through the wireless network;
transmitting, by the wireless network, to the UE, a notification of network congestion; and
transmitting, by the wireless network, to the UE, a retry parameter set for retrying initiation of the first data session, the retry parameter set including a fast retry time interval for attempting a maximum number of fast retries of initiation of the first data session at the fast retry time interval, and a slow retry time interval for retrying initiation of the first data session at the slow retry time interval.
